The storage tank holds about 2 gallons but you could always use cleaned plastic bottles to hold more if you need more on hand. If I constantly draw/refill it over the day I could get 8-10 gals per day from it.

They're a bit pricey - $200+ - but they do 10,000 gallons and if you are only using it to get the minerals and chemicals out of your tap water you can clean and reuse the ceramic filters. Over time it's certainly cheaper than buying bottled water.
I'll definitely look into it, but not sure about the differences between this and RO, which is what mistkings recommends. And 200 isn't a big deal, some of the units I was looking at were like 600+, they were just sort of nice kitchen appliances, whereas I care less for aesthetics and more for functionality.
